Migrating from Webrat to Capybara...unsuccessfully
Hoping someone might see what I've overlooked...
I'm trying to get Capybara working in a small existing application...and I'm not having any luck.
Gemfile:
group :development, :test do
gem 'rspec-rails'
# gem 'webrat'
gem 'capybara', :git => 'git://github.com/jnicklas/capybara.git'
end
...
Similar specs in two places are failing for different reasons. Not sure why?
spec/controllers/pages_controller_spec.rb:
require 'spec_helper'
describe PagesController do
describe "GET 'about'" do
it "should be successful" do
# get 'about' #worked w/ webrat
# response.should be_success #worked w/ webrat
visit pages_about_path
# page.should have_content('About Us')
page.html.should match(/About/i)
e开发者_Go百科nd
it "should have title" do
# get 'about' #webrat
# response.should have_selector("title", :content => "About Us") #webrat
visit pages_about_path
page.should have_selector("title")
end
end
end
Failures:
(may be pulling in some generic page as doctype in browser is "<!DOCTYPE html>")
1) PagesController GET 'about' should be successful
Failure/Error: page.html.should match(/About/i)
expected "<!DOCTYPE html PUBLIC \"-//W3C//DTD HTML 4.0 Transitional//EN\" \"http://www.w3.org/TR/REC-html40/loose.dtd\">\n\n" to match /About/i
# ./spec/controllers/pages_controller_spec.rb:13:in `block (3 levels) in <top (required)>'
2) PagesController GET 'about' should have the right title
Failure/Error: page.should have_selector("title")
expected css "title" to return something
# ./spec/controllers/pages_controller_spec.rb:20:in `block (3 levels) in <top (required)>'
spec/views/pages/about.html.haml_spec.rb:
require 'spec_helper'
describe "pages/about.html.haml" do
it "renders attributes in <p>" do
# render #webrat
# rendered.should match(/About/) #webrat
visit pages_about_path
page.should have_content("About Us")
end
it "should have the right heading" do
# render #webrat
# rendered.should have_selector("h2", :content => "About Us") #webrat
visit pages_about_path
page.should have_selector("h2")
end
end
Failures:
1) pages/about.html.haml renders attributes in <p>
Failure/Error: visit pages_about_path
NoMethodError:
undefined method `visit' for #<RSpec::Core::ExampleGroup::Nested_1:0x00000101dc2970>
# ./spec/views/pages/about.html.haml_spec.rb:8:in `block (2 levels) in <top (required)>'
2) pages/about.html.haml should have the right heading
Failure/Error: visit pages_about_path
NoMethodError:
undefined method `visit' for #<RSpec::Core::ExampleGroup::Nested_1:0x000001034b1d98>
# ./spec/views/pages/about.html.haml_spec.rb:16:in `block (2 levels) in <top (required)>'
Just had the same issue and found that capybara needs:
response.body.should have_selector("title")
webrat does not need the .body
also, make sure you are rendering views eg:.
describe PagesController do
render_views
You should include capybara DSL in your test file :
require 'spec_helper'
describe PagesController do
include Capybara::DSL
describe "GET 'about'" do
it "should be successful" do
...
This won't fix all your problems, but Instead of:
page.html.should match(/About/i)
try:
page.should match(/About/i)
(you might not even need page).
Also, check that you have Capybara set to use CSS queries in env.rb (it defaults to XPath).
Ensure that your spec_helper.rb file has the following at the top:
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'
require 'capybara/rspec'
I had a similar issue as yours (i.e., undefined method 'visit') and popping those lines solved the issue.
